U+F908 "龜" CJK Compatibility Ideograph-# Unicode Character

U+F908 "龜" CJK Compatibility Ideograph-# is a character originally designated for compatibility with pre existing East Asian character encoding standards, specifically representing a variant form of the Chinese character for "turtle" or "tortoise." It belongs to the CJK Compatibility Ideographs block, which was created to map characters that had been unified with other ideographs in the main CJK Unified Ideographs block but retained distinct shapes in older standards. This particular character is a duplicate of the standard CJK Unified Ideograph U+9F9C "龜" (guī in Mandarin, meaning turtle or tortoise), and it is rarely used in modern text, serving mostly as a historical artifact for round trip conversion with legacy systems.
